The 1st North American Riichi Open is a tournament held on June 13-14, 2015 at Montreal (Quebec), Canada.
Name
As the name implies, it purports to be the first open ([fr] omnium) tournament in North America for riichi mahjong. The criteria for this are:
- Open access to anyone.
- Three-month advance notice.
- Related to Japanese mahjong.
There have been many things called "tournaments" in North America: it is not the organizer's goal to mock previous events but to propose a better standard, similar to what is occuring in Europe at this time.
Location
The tournament was held in room E-3313 at the Collège de Maisonneuve (3800 Sherbrooke East) in the South wing. The college itself is within walking distance from the Stade de Olympique (Olypic Stadium)[1].
Cost
Participants paid a tournament fee of 40 CAD per person. Costs were kept as low as possible to address budgetary concerns.
Rules
While not denying the need for a global standard, the organizer decided that for a first tournament, the rules would attempt to make a suitable hybrid between local rules and the World Riichi Championship rules used previously in 2014 in Puteaux, France.
Basic settings
- Type: Ari-ari mahjong.
- Points: 30,000 to start, busting ends the game.
- Dora: All standard dora, kandora follow late flip rules.
- Chombo: 10,000 point deduction, done at the end of the game (a delayed negative score), affecting table placement. {Revised March 1.}
- Call priority: 0.5 seconds. Ron calls have a three second window regardless of other calls.
- Red fives: None.
- Games end at South 4 or when someone busts.
- Rank bonus (jun’iten/uma): 5-15, as per WRC2014 rules
Yaku and scoring options
- No abortive draws
- No counted yakuman. (11+ han = sanbaiman)
- No multiple yakuman. (Absolute limit of 32,000/48,000)
- No renhou or paarenchan.
- No ryanhan shibari.
- Tenpai-renchan.
- Proper furiten required.
- Last-hand riichi sticks are removed from the game.
Faults and fouls
- 1 to 5 tiles (from anywhere but opponent's hands) = 1,000 pt deposit.
- 1 to 5 tiles from an opponent's hand = dead hand.
- 6+ tiles from anywhere = chombo.
- False ron call with no tiles shown = dead hand.
- False ron call with tiles shown = chombo.
- Illegal upgrade of a call = chombo.
(Legal upgrade: Any variation of "po-ron" or "pon, I mean ron" done quickly (0.5 seconds) prior to tiles being exposed is tolerated. Taking much longer, or exposing two tiles then calling ron is illegal.)
Extra rulings
- Scoring sheets (for marking the final game score) along with a point grid will be provided.
- Yaku sheets are not provided: players with them may not consult them during a match (from East 1 to South 4).
- Violations of the rules are potentially subject to 10,000 point deductions.
- Cheating will lead to immediate expulsion. Standards of proof are not subject to debate.
- Self-arbitration is both encouraged and required. The referee is responsible for the tournament, not for each individual.
- Scoring is done with point sticks: please overpay quickly and efficiently. Do not dive for 26 green sticks for payment.
- All calls should be vocalized cleanly and effectively. If you have a problem articulating P/R, or in general: let the table know. If the table has to warn a player twice, the third time may be subject to a dead hand ruling.
- No foreign objects allowed on the game tables. Placing a beverage, food or a rack/ruler (or anything else not necessary) on a game table is subject to a 10,000 point deduction per violation.
